`help` argument for options
Non global (local) options can be added to modes
`local` added to list of legal option keys in clap/builder.py
Nested parsers got type handlers applied (JSON)
Changes in help message generation
Single parser functionality moved to modes parser - first step to the
unification of parsers
Version bumped
Moved option regexps and lookslikeopt() function to shared
Removed all traces of old code dependent on clap.base import from `clap.checker.Checker()`
Removed all traces of old clap.parser.Parser from tests.py
(these will later be added when the code from clap.modes will
be moved to clap.parser but now it's convinient)
Fixed bug which caused a crash in clap.modes.Parser if it contained options which had no arguments
Mode information are now private
Fixed a typo in docstring in clap/base.py
Removed unused debug print() message (it was telling the type of checked
parser)
Merged ParserTests and ModesTests
Information about parsed options and operands are now private and
should be accessed via getters()
Unified single and nested-mode parsers, clap.modes.Parser is now
officially deprecated
Implemented overloaded == operator for clap.base.Base and
clap.parser.Parser
Version bumped to 0.9.0
